Parses and fully dereferences OpenAPI 3.0+ specifications using @apidevtools/swagger-parser, resolving all $ref pointers and external schema definitions into a unified in-memory representation. Handles both local file paths and remote URLs, normalizing the specification structure for downstream tool extraction and validation schema generation.
Unique: Uses @apidevtools/swagger-parser for full dereferencing with automatic $ref resolution, rather than naive regex-based reference handling, ensuring complex nested schemas and external definitions are correctly flattened into a single canonical representation
vs alternatives: More robust than manual OpenAPI parsing because it handles recursive $refs, external schema files, and circular references automatically, whereas custom parsers often fail on complex real-world APIs
Converts OpenAPI paths and operations into McpToolDefinition[] array by extracting operation metadata (operationId, summary, description), parameter schemas, request/response bodies, and HTTP method details. Maps REST semantics (path params, query params, headers, request bodies) to MCP tool input schemas with proper categorization and naming conventions.
Unique: Implements extractToolsFromApi() function that maps REST operation semantics directly to MCP tool contracts, preserving parameter types, required fields, and descriptions in a single pass, rather than requiring manual tool definition or separate schema transformation steps
vs alternatives: Faster and more accurate than manual tool definition because it automatically extracts all operation metadata from OpenAPI in one pass, whereas manual approaches require developers to re-specify each parameter and description
Proxies validated MCP tool calls to target REST APIs using axios HTTP client, handling request construction (method, URL, headers, body), response parsing, and error handling. Automatically constructs URLs from OpenAPI path templates and parameters, injects authentication headers, and returns API responses to MCP clients with appropriate status code and body mapping.
Unique: Uses axios to construct and execute HTTP requests based on OpenAPI operation definitions, automatically mapping MCP tool inputs to REST parameters (path, query, body) and handling response parsing, whereas manual proxying requires explicit URL construction and header management
vs alternatives: More maintainable than manual HTTP construction because URL templates, parameter mapping, and headers are derived from OpenAPI definitions, reducing the risk of mismatches between spec and implementation
Exports McpToolDefinition type and other type definitions for use in generated code and programmatic API, providing TypeScript type safety for tool definitions, input schemas, and configuration objects. Type definitions are included in the generated project's tsconfig.json and enable IDE autocomplete and compile-time type checking.
Unique: Generates and exports McpToolDefinition type alongside code, enabling type-safe programmatic API usage and IDE support in generated projects, whereas many generators only produce untyped JavaScript output
vs alternatives: More developer-friendly than untyped code because TypeScript type checking catches errors at compile time and IDEs provide autocomplete, whereas untyped approaches require runtime testing to catch type mismatches
Generates package.json with all required runtime dependencies (@modelcontextprotocol/sdk, axios, zod, Hono for web/HTTP transports) and development dependencies (TypeScript, @types packages), with pinned versions for reproducibility. Includes scripts for building, running, and testing the generated server, making the project immediately deployable with npm install && npm start.
Unique: Generates transport-specific package.json with only required dependencies (e.g., Hono only for web/HTTP transports, not for stdio), reducing bundle size and dependency bloat compared to generators that include all optional dependencies
vs alternatives: More efficient than monolithic dependency lists because transport-specific dependencies are only included when needed, whereas generic generators include all possible dependencies regardless of transport mode
Transforms OpenAPI JSON Schema definitions into executable Zod validation code via json-schema-to-zod library integration. Generates TypeScript code strings that define Zod schemas for request/response validation, handling type mappings (string, number, boolean, object, array), constraints (minLength, maxLength, pattern, enum), and nested object structures.
Unique: Leverages json-schema-to-zod library to automatically transpile JSON Schema constraints into Zod validation code, enabling runtime type checking without manual schema duplication, whereas most generators either skip validation or require hand-written schemas
vs alternatives: More maintainable than manual Zod schema writing because schema definitions stay in OpenAPI and are auto-generated, reducing drift between API documentation and validation logic
Generates complete TypeScript MCP server implementations supporting three transport modes: stdio (standard input/output for local processes), SSE (Server-Sent Events via Hono web server for browser clients), and streamable-http (HTTP with streaming responses via Hono). Each transport generates transport-specific entry points (index.ts for stdio, web-server.ts for SSE, streamable-http.ts for HTTP) with appropriate request/response handling and dependency injection.
Unique: Generates transport-specific entry points from a single OpenAPI spec, with Hono-based web/HTTP servers and native stdio support, allowing the same API to be deployed as a CLI tool, web service, or HTTP endpoint without code duplication
vs alternatives: More flexible than single-transport generators because it supports three distinct deployment models from one spec, whereas most MCP generators only support stdio or require manual transport layer implementation
Parses and respects the x-mcp OpenAPI extension to selectively include or exclude operations from MCP tool generation. Allows API developers to annotate operations with x-mcp: {enabled: false} to hide internal or deprecated endpoints from MCP exposure, providing fine-grained control over which REST operations become MCP tools without modifying the OpenAPI spec structure.
Unique: Implements custom x-mcp OpenAPI extension for declarative operation filtering, allowing API specs to define MCP visibility inline without external configuration files, whereas most generators expose all operations or require separate allowlist/blocklist files
vs alternatives: More maintainable than external filtering configs because visibility rules stay in the OpenAPI spec alongside operation definitions, reducing configuration drift and making intent explicit to API maintainers

Executes SQL queries against Supabase PostgreSQL instances through the Model Context Protocol, translating natural language or structured query requests into parameterized SQL statements. Uses MCP's tool-calling interface to expose database operations as callable functions with schema validation, enabling LLM agents to perform CRUD operations, joins, and aggregations with automatic connection pooling and credential management through Supabase client SDK.
Unique: Exposes Supabase PostgreSQL as MCP tools with automatic credential injection from Supabase client SDK, eliminating manual connection string management and enabling seamless LLM-to-database queries within Claude or compatible agents
vs alternatives: Tighter integration than generic SQL MCP servers because it leverages Supabase's built-in authentication and connection pooling rather than requiring separate database credential configuration
Exposes Supabase Auth session state and user metadata through MCP tools, allowing agents to inspect current authentication context, retrieve user profiles, and trigger auth-related operations. Integrates with Supabase's JWT-based auth system to validate sessions and access user claims without re-authenticating, using the Supabase client's built-in session management.
Unique: Integrates Supabase's JWT-based auth system directly into MCP tool interface, allowing agents to inspect and act on auth state without managing separate credential stores or re-authentication flows
vs alternatives: More seamless than generic auth MCP servers because it leverages Supabase's built-in session management and avoids redundant credential passing between agent and auth system
Invokes Supabase Edge Functions (serverless TypeScript/JavaScript functions) through MCP tools, passing parameters and receiving results with optional streaming support. Uses Supabase's edge function HTTP API to trigger functions with automatic authentication headers and response parsing, enabling agents to execute custom business logic without embedding it in the agent itself.
Supabase scores higher at 42/100 vs openapi-mcp-generator at 29/100.

Unique: Exposes Supabase Edge Functions as MCP tools with automatic authentication and response parsing, allowing agents to invoke custom serverless logic without managing HTTP clients or credential injection
vs alternatives: More integrated than generic HTTP MCP tools because it handles Supabase-specific authentication, error handling, and response formatting automatically
Subscribes to real-time changes on Supabase tables through MCP's event streaming interface, using Supabase's PostgreSQL LISTEN/NOTIFY mechanism to push INSERT, UPDATE, and DELETE events to agents. Maintains persistent WebSocket connections and filters events by table and row-level policies, enabling agents to react to database changes without polling.
Unique: Bridges Supabase's PostgreSQL LISTEN/NOTIFY real-time system with MCP's tool interface, enabling agents to subscribe to database changes without managing WebSocket connections or event serialization
vs alternatives: More efficient than polling-based approaches because it uses Supabase's native real-time infrastructure rather than repeated database queries
Manages files in Supabase Storage buckets through MCP tools, supporting upload, download, list, and delete operations with automatic authentication and path-based access control. Uses Supabase's S3-compatible storage API with built-in support for public/private buckets and signed URLs for temporary access, enabling agents to handle file I/O without managing cloud storage credentials.
Unique: Exposes Supabase Storage's S3-compatible API as MCP tools with automatic authentication and signed URL generation, eliminating the need for agents to manage cloud storage credentials or generate temporary access tokens
vs alternatives: More integrated than generic S3 MCP tools because it leverages Supabase's built-in bucket policies and authentication rather than requiring separate AWS credentials
Performs semantic similarity searches on vector embeddings stored in Supabase PostgreSQL using pgvector extension, translating natural language queries into embedding vectors and executing cosine/L2 distance searches. Integrates with embedding providers (OpenAI, Cohere) or uses pre-computed embeddings, enabling agents to retrieve semantically similar documents or records without full-text search limitations.
Unique: Integrates pgvector directly into MCP tools with automatic embedding generation and distance calculation, enabling agents to perform semantic search without managing separate vector database infrastructure
vs alternatives: More efficient than external vector databases (Pinecone, Weaviate) for Supabase users because it colocates embeddings with relational data, reducing network latency and simplifying data synchronization
Exposes Supabase database schema information through MCP tools, allowing agents to discover table structures, column types, constraints, and relationships without manual schema documentation. Queries PostgreSQL information_schema and Supabase metadata tables to dynamically generate schema descriptions, enabling agents to construct valid queries and understand data relationships.
Unique: Queries Supabase's PostgreSQL information_schema directly through MCP tools, enabling agents to dynamically discover and adapt to database schemas without pre-configured schema definitions
vs alternatives: More flexible than static schema definitions because it reflects live database state, including recent migrations or schema changes
Enforces Supabase Row-Level Security policies within agent queries, ensuring that agents can only access rows permitted by RLS rules defined in the database. Evaluates policies based on authenticated user context (JWT claims, user ID) and applies WHERE clause filters automatically, preventing unauthorized data access at the database layer rather than application layer.
Unique: Delegates authorization enforcement to PostgreSQL RLS policies rather than implementing authorization in agent code, ensuring that data access rules are centralized and cannot be bypassed by agent logic
vs alternatives: More secure than application-level authorization because RLS is enforced at the database layer, preventing accidental data leaks even if agent code has bugs
